GDXray [1]} was first introduced in 2015 and it contains 19,407 high-resolution grayscale X-ray scans. The dataset is primarily designed for the non-destructive testing purposes and the scans within GDXray [1]} are arranged into five categories, i.e., welds, baggage, casting, settings and nature. But baggage is the only relevant group for this study and it contains 8,150 grayscale X-ray scans. Moreover, the dataset also presents the detailed annotations for the prohibited items such as shuriken, knives, guns, and razors. As per the dataset standard, 400 scans from GDXray [1]} were used for training purposes, while the remaining scans were used for testing purposes.
